(5) Adjust an executive task, the number of transfer word referring to the operation
processing time so that this instruction may not obstruct the execution of the
motion operation because processing time becomes long in argument to the
number of words (n) to be written.
(1) An operation error will occur if:
• Number of words (n) to be written is outside the range of 1 to 256.
• The CPU shared memory address (D) of self CPU of the writing destination
device is outside the range (800H to FFFH) of the CPU shared memory
address.
• The CPU shared memory address (D) of self CPU of the writing destination
device + number of words (n) to be written is outside the range (800H to FFFH)
of the CPU shared memory address.
• Start device No. (S) which writing data are stored + number of words (n) to be
written is outside the device range.
• MULTW instruction was executed again before MULTW instruction is executed
and complete bit device is turned on.
• (D1) is a write-disabled device.
• (S) is a bit device and device number is not a multiple of 16.
• PX/PY is set in (S) to (S)+(n-1).
